Set in Portland, the story follows Lux Cassidy, a teenager who was given up at birth and has spent her life in foster care who finds her biological parents Nate Bazile and Cate Cassidy. Wishing to become emancipated, Lux is instead given in to their custody.

While Life Unexpected received mostly positive reviews, it struggled in the ratings and was cancelled by The CW in 2011. The show has since been released on DVD and it is also available on Netflix.com through their streaming service.

Lux Cassidy (Britt Robertson) had been through the foster care system for almost her whole life.( until she was 16) Cate Cassidy (Shiri Appleby) had given birth to her while at age 16, but gave her up for adoption after being promised by Social Services that the baby would quickly be adopted. Due to heart problems as a baby (she had ventricular septal defect), and countless surgeries, she was not a desirable candidate for adoption, and instead ended up in the foster care system and in and out of group homes. Just before her 16th birthday, Lux is petitioning the court to become an emancipated minor, but before that occurs, she must get signatures from her unknown birth parents. She first finds her father, Nate Bazile, operator of the Open Bar, a business he operates out of a building given to him by his father. Baze lives a semi-fraternity boy lifestyle above the drinking establishment with two roommates, Math (Austin Basis), a high school teacher and Baze's childhood best friend, and Jamie (Reggie Austin), who also works at the bar. However, even when he signs the papers, Baze discovers that he is already bonding with his newfound daughter, and realizes that she has his eyes. He introduces Lux to her mother Cate Casidy, co-host of the "Morning Madness" drive time show at Portland radio station K-100 and Baze's former one-night stand from high school. Lux has been listening to Cate's voice on the radio as long as she can remember, so she feels an instant connection with the mom she's never met. Baze takes Lux to meet Cate, who is shocked and saddened to learn that Lux has grown up in foster care instead of the adoption she believed would take place, and is reluctant to commit to her daughter. Eventually, Cate wants to be a part of Luxs' life, and she shows that she really does care.

When a judge decides that Lux isn't ready for emancipation and unexpectedly grants temporary joint custody to Baze and Cate, they agree to try to get past the awkwardness. Cate, due to her job as a radio host, and the fact that she has a suitable house, is given primary custody of Lux. Ryan Thomas (Kerr Smith), her radio broadcast partner, as well as her fiance, also takes to Lux and has bonded with her as well, sometimes being able to get through to her better than her parents, due to similar issues that they have had.

As the series progresses, though, Baze becomes more responsible, and works harder to get the bar and the loft apartment above it in shape so that Lux can be able to visit and stay with him. He eventually succeeds in this by setting aside a corner of his loft as a bedroom for Lux. Due to their close bond, Baze, the one that was considered to perhaps be more of a slacker, had proven that when the chips are down, he inevitably comes through for Lux, giving her support and love. Cate, despite constantly disappointing Lux, still means well. Her radio show is produced by Alice (Erin Karpluk), who often serves as her confidante.

Ryan, in some ways jealous and insecure because of Baze's constant presence in his fiancee's life, gets resentful and has physically fought Baze. Ryan, finally fed up with Baze's continual interference, breaks it off with Cate. Eventually though, Ryan and Cate reconnect, and their engagement is back on. He also relents a bit towards Baze after the two have drinks and Baze explains that all he is to Cate is the father of Lux, and nothing else. By the series end, though, Baze and Ryan are good friends.

Baze's bar is owned by his father Jack (Robin Thomas), who considers Baze a disappointment, but softens towards him somewhat in later episodes, due to Lux's entrance in their lives. Baze himself later buys the bar. Also seen is Cate's four-times-divorced mother whose idea it was to convince Cate into giving up Lux; and Baze's level headed and more understanding mother, Ellen (Susan Hogan). Both of them meet Lux, and both of them love her, although Ellen seems to have the stronger grandmotherly bond with her.

After attending Longfellow High, a rough high school in Portland, Cate registers Lux at Westmonte High, the school she, Baze and Math all attended (and where Math himself works as a teacher), this development, at first, infuriates Lux; but she adapts, makes friends and meets her later boyfriend, popular student, Jones Mager (Austin Butler) who, like his father, is also very good at running track.

Lux has several friends from her old life, including her childhood best friend Tasha Siviac, whom she has known since she was seven (they had met at Sunnyvale, the foster care home); Lux' first boyfriend Bug, and Tasha's boyfriend Gavin. She must decide whether she can continue to have her old friends in her life as she attempts new friendships. Sometimes, Bug is known for doing things which brings her in trouble with the law, and that sometimes imperils Lux's life with Baze and Cate. Her case is handled by her longtime social worker, Fern Redmund, who is also instrumental in helping Cate and Baze get their parental rights reinstated, which does happen, and they become a family, officially. Due to this, Fern becomes a family friend.

Baze, at variant times, incurs Cate's wrath when it is discovered that he is sleeping with her younger sister and Lux's aunt, Abby, who is a neurotic therapist and practitioner of yoga. Baze also slept with Ryan's sister Paige after a drunk incident in season two. Lux meets a young man at Baze's bar, Eric Daniels, and goes on a date with him, only to later find out he is her new teacher.

The second season deals with Lux's affair with her teacher, which was ended when Eric left town on Cate and Baze's orders that they would call the police if he didn't resign his job and leave Portland; Cate and Ryan's new marriage and their attempts to have a child, and Baze's relationship with his coworker Emma Bradshaw and her son Sam.

Later on, Tasha (who lives on her own now, due to independent living) becomes more of a part of the family's life (Bug and Gavin both are no longer seen, Bug having left town after Lux turning down his engagement) and is often seen with her best friend Lux.

Cate miscarried her child with Ryan because of some condition that she developed after having Lux and that, due to the condition, Lux would be the only child she would ever have. This news created a stronger bond between Cate and Lux, and Lux finally realizes that her mom loves her and won't let any harm come to her. After nearly giving in to his desire for her, Baze breaks it off with Emma in the wake of learning from Lux that Emma had had an affair with his dad; not when he was going out with her, but his dad cheated on his mother. Baze stated that he could never be with Emma without thinking of his father.

The show then fast-forwards two years at which point Lux is delivering the commencement speech at her graduation. It is revealed that Ryan and Julia are together and have a young son from their affair. And, of course, Baze and Cate are finally together as a couple, kissing to reveal it. Math and Alice are married and are expecting a child. Jones also kisses Lux, revealing that they end up together and Tasha is happy for them. Lux and Tasha prepare for college in Eugene. At the end, the family and friends take a photo together.

Creator Liz Tigelaar came up with the idea for the show in 2007 and developed it with director Gary Fleder.[1] Tigelaar and Fleder pitched the show, then titled Light Years, to ABC Studios who accepted it. They then sold the show to The CW. In September 2008, The CW ordered the show to pilot.[2] After the pilot was ordered, ABC then dropped the show for financial reasons.[3] The show was then picked up by CBS Television Studios. The pilot was filmed in January 2009, being written by Tigelaar and directed by Fleder. Both also served as executive producers.

The CW announced the series in January 2009 under the working title of Light Years because the main character Lux's name means Light.[4] According to Tigelaar, the title "tested way too sci-fi"[5] and it was changed to LUX (the name of one of the lead characters) in April. This was quickly changed again into Life Unexpected, but at The CW Upfronts in May, the series was promoted as Parental Discretion Advised.[6][7] That June, the network reverted to the name Life UneXpected, again highlighting the name of the main character in capital letters. Initial advertising for the series in fall 2009 listed it without the capitalized "X", which became the final version as it appears now.

The show premiered on The CW on Monday, January 18, 2010. The 13-episode first season run ended on April 12, 2010. The series was picked up for a second season, for an initial thirteen episode order, which premiered on September 14, 2010, airing on Tuesdays at 9/8c following One Tree Hill.[10][11]

In October 2010, The CW ordered two additional scripts.[12] In November 2010 The CW declined to order the back 9 episodes for the show's second and final season, leaving the season's episode count at 13.[13] Members of the cast campaigned to save the show.[14] On December 6, 2010, series creator, Liz Tigelaar made the TV show's cancellation official via Twitter.[15][16]

In an attempt to improve Life Unexpected's ratings by attracting One Tree Hill viewers, The CW aired a crossover event involving both programs on October 12, 2010.[17] Beginning with One Tree Hill installment "Nobody Taught Us to Quit", Haley James Scott (Bethany Joy Lenz) and Mia Catalano (Kate Voegele) traveled to Portland (where Life Unexpected is set) to perform at the Sugar Magnolia Music Festival hosted by K-100. Haley and Cate meet in the crossover and are "surprised to learn that they share a similar back story [as] mothers." "Music Faced," the Life Unexpected episode of the crossover, also featured Sarah McLachlan, Ben Lee and Rain Perry whose song "Beautiful Tree" serves as the series' opening theme.

The first season of Life Unexpected scored a 69 out of 100 on Metacritic.[18] The series has garnered mostly positive feedback, with many reviews favorably comparing the show to the critically acclaimed series Gilmore Girls and Everwood.[19][20][21][22][23] Maureen Ryan, from the Chicago Tribune, stated that the show "recall[s] the good things about shows like Gilmore Girls and Everwood,"[21] and similarly, Hank Stuever from The Washington Post called it "a pleasant mix of a little Juno hipitude and a lot of Everwood glow."[22] Furthermore, the Chicago Tribune review called Life Unexpected a program "that parents and their older kids could enjoy together without feeling condescended to,"[21] and The Boston Globe's Matthew Gilbert states that "the show works, in its own hokey, feel-good, alt-soundtrack way."[24]

On a negative note, a review in the Chicago Sun Times by Paige Wiser called the show "somewhat predictable"[20] and The Post's Stuever adds that Life Unexpected "burns off its most interesting plot twist [...] in the first 20 minutes."[22]

After going from foster home to foster home her whole life, fifteen-year-old Lux applies for emancipation from the foster care system. The paperwork requires the signatures of both of her birth parents, neither of whom she has met. Lux tracks down Baze, her father, to the bar he owns and lives above with his friends, and he tells her her mother is local radio personality Cate Cassidy. At the hearing the next day the judge rejects Lux's petition and places her instead in the temporary joint custody of Cate and Baze, to everyone's surprise. After breaking up with her fiancé, Ryan, Cate unexpectedly sleeps with Baze.

Lux temporarily moves in with Cate, who is very worried about what Child Protective Services will think of her and Baze as parents. At work Cate is asked to read a statement over the radio denying she had a baby in high school, which a hurt Lux hears over the radio. After realizing how much she has hurt Lux, Cate sets the record straight on the radio the next day. Cate and Baze impress Fern, the CPS worker, who grants them permanent custody of Lux.

Cate reluctantly attends a dinner for Lux at Baze’s parents' house, and the situation becomes complicated when Cate’s mother Laverne and sister Abby arrive unexpectedly. Meanwhile, worried about Lux's safety at her school, Cate arranges for her to transfer to Westmonte High, where Cate and Baze graduated. When Baze's father threatens to take away the bar because Baze can't pay the rent, Lux uses her own money to pay Baze's rent.

After Lux is suspended from school, Cate desperately tries to get Lux's principal to drop the suspension. To get the principal's sympathy for Lux, Cate brings Lux's foster care file to the meeting with the principal, and another student manages to photocopy the file. Lux is distraught when photocopies from the file are stuck to her locker the next day for everyone to see. Meanwhile, Baze is upset when he discovers Cate and Ryan will host a radio station event at a competing bar.

Lux volunteers to host a classmate's party at Baze's loft, hoping to become more accepted by the students at her new school, but this fails when Baze finds out and lectures her about what she did. (This shows that Baze is shaking off his semi-frat boy behavior in favor of him becoming a father). Cate sees that Baze and Lux have made a great connection and she worries that she will never have a similar relationship with Lux.

Baze joins Ryan and Cate on "Morning Madness" because of pressure from the station management, but the show does not go as expected. Worried about her boyfriend, Lux must convince Jones Mager, a popular high school track star, to not press charges against him.

Jones asks Lux to the Winter Formal, but things become complicated with Bug returns to town. Recalling that the night of his Winter Formal was the night he and Cate conceived Lux, Baze decides to enlist Cate's therapist sister Abby to help him give Lux a sex talk. However, when Baze finds a condom in Lux's room later that night, he decides to go to the formal to check up, worrying that Lux hadn't listened. Cate is also at the formal, having volunteered to chaperon so she can see Lux in her dress. A fragile Baze sleeps with Abby after the formal.

Fern, Lux's social worker meets with Cate and Baze after Bug and Lux are picked up by the police. Cate tries to get Bug a job at the radio station, but her boss will not hire him as he wasn't as experienced as he needed to be. She becomes enraged after finding out Baze hires Bug, accusing him of undermining her attempts to make things right with Lux, since Lux became greatly upset that Cate said she could get him a job, but didn't. Lux tearfully tells her parents the truth about her feelings towards Cate's lack of concern while she was in foster care.

Cate discovers Abby and Baze have been sleeping together. Despite rejecting Jones at a party, Lux is hurt when later that same night she sees him kissing another girl.

People from Bug's past trash Baze's bar when Bug can't pay them the money he owes them, forcing Lux to get Baze away from the bar for a few days so Bug can clean it up. Lux pleads with Cate to allow Baze to go on the trip to meet Cate's father, and the three of them go on a family road trip. Cate's father hurts her when she realizes he does not want to be a father to her, and she and Baze bond on the trip.

Cate's quickly approaching wedding forces her to deal with her feelings for both Ryan and Baze. Feeling he is not good enough for Cate, Baze denies he has feelings for her and Cate resolves to marry Ryan. Lux desperately tries to convince both Cate and Baze to admit their feelings, but a conversation with Ryan makes her think Cate and Baze together can never be more than a fantasy. After a heart-felt conversation with his father, Baze rushes to the church to tell Cate he loves her, although he was stuck in traffic that delayed him to bursting in through the doors, after as the priest marries them.
